morpheus programe

Installed morpheus preview edition out of curiosity and was not impressed by it. Un-installed the programe from add/remove programe and from the registry. After browsing the net an icon appears on my desktop as “rdxr020305.dat”. Deleting it does nothelp as it re-appears. It is not present in the registry and not a virus. How do i get rid of it without re-installing windows 98.
